Energy Star 3.0 regulations set to impact TV designs

by Steven Kim posted Aug 3rd 2009 at 6:38PM

Energy Star logoIf you thought there was a row over the Energy Star 3.0 requirements for TVs, you haven't seen anything yet. Research firm iSuppli rightfully calls out some challenges for even the energy-miserly LCD TVs to duck under the numbers in the draft version of the Tier 2 (effective 2010) and Tier 3 (effective 2012) versions of the standard. For example, a 50-inch TV will have do limbo underneath a 153-Watt peak for Tier 2 compliance and 108-Watts for Tier 3. We're confident that some clever engineering will allow LCD to reach those figures; the real impact might be on plasma TVs, however. It pains us to say it, but plasma's going to have a hard time making that grade; of course, that's assuming that plasma TVs are still being made and marketed towards consumers who value the Energy Star label. For those of us who want efficiency and ultimate image quality, it's time to pull for LED-backlit LCDs.

Scientists purportedly improve blue OLED efficiency by 25%

by Darren Murph posted Mar 23rd 2009 at 3:43AM


The holy grail of OLED is upon us. With scientists around the world working to improve efficiency of the short-lived blue OLED in order to better align with lifespans of the green and red counterparts, a team from Pacific Northwest National Laboratory has reportedly taken a huge leap in solving the whole thing. These gurus have conjured up new host materials for a blue phosphorescent OLED that's at least 25 percent more efficient than existing blue OLEDs, but regrettably, details beyond that are few and far between. Word on the street has it that PNNL scientists are expected to gather and discuss the findings before heading to a meeting of the American Chemical Society later this spring, and we'll be crossing our fingers that whatever they've found is both a) cheap and b) easily implementable.

Plasmas from Hitachi, Pioneer, LG, Panasonic break onto the Energy Star list

KURO Energy Star
Not to be outdone by their LCD brethren, plasma displays from Hitachi, LG, Panasonic and Pioneer have earned the right to wear Energy Star badges (or sashes). All told, 43 models from the manufacturers successfully navigated the 208-Watt "on mode" and less than 1-Watt "standby mode" limbo stick, and although the Plasma Display Coalition isn't crowing about smashing the requirements like JVC did with its LCDs, it's still a testament to advances to plasma efficiency. For us plasma-philes here at Engadget HD, knowing our obsessive pursuit of image quality isn't destroying the planet is a bit like having our cake and eating it, too.

LG shuts doors on A1 plasma manufacturing plant

by Darren Murph posted May 21st 2007 at 10:17AM


While some may have balked at Sony taking an early exit from the PDP market, LG is becoming the fourth major player to reevaluate its investment in plasma after Philips was caught claiming that LCD TVs would likely shape its strategy and Hitachi began to look intently overseas for buyers. Reportedly, LG is closing the doors of its oldest plasma manufacturing plant in Gumi, South Korea as it hopes to "increase operational efficiency and reduce costs." The removal of the A1 plant will drop its plasma capacity from 430,000 to 360,000 panels this year, and it should save the company somewhere between "$22 million and $32 million per year." Notably, LG currently sits in second place in quantity of PDPs shipped worldwide, but considering the perpetual nosedive of HDTV prices over the past year or so, we can't say that Life looks too Good in the PDP arena right now.
